3Specifications and Intended Use
3.1 Scope of Use
Rotork SPI units are valve position indicators. They are designed to be mounted to an actuating gearbox, or
directly mounted to smaller valves for either non-thrust taking, or with the addition of a thrust base
assembly, thrust taking applications.
The unit is designed to mechanically indicate valve position locally, and electrically signal open / close
position of the valve to a remote location, as well as transmit the required operating torque to the valve
actuating gearbox or valve via an input shaft mounted handwheel.
Rotork products should not be modified in any way nor should any parts be removed without first consulting
Rotork. For applications outside of this scope, please contact Rotork. The user alone is responsible for the
appropriate use of the SPI in consideration of the basic conditions existing at the plant.

PUB132-002-00_0219
5Unpacking & Handling
SPI units are packed in a variety of configurations depending upon the application, size of the actuating
gearbox mounted to and the quantity of the consignment. Therefore it is the responsibility of the individual
unpacking and handling the unit to carry out a risk assessment for the particular consignment and to unpack
and handle accordingly using safe working practices. The packaging should be re-used or recycled according
to local regulations. The packaging materials used are wood, cardboard, paper, steel and polyethylene. SPI
units should be lifted using soft slings (where required) and care should be taken not to apply any shock
loads. The individual risk assessment should identify which part of the SPI and or actuating gearbox should
be used for lifting. Once the SPI or actuating gearbox combination is fitted to the valve, the assembled valve,
gearbox and / or SPI must not be slung from the gearbox or SPI unit.
⚠WARNINGS ⚠
⚠Individual weights for actuating gearboxes and SPI units are recorded on their respective nameplates;
actuating gearboxes and SPI units may present an unbalanced load.
⚠Only trained and experienced personnel should carry out handling. At all times, safe handling must be
ensured.
⚠Each assembly must be assessed to identify all risks associated with handling.
⚠The actuating gearboxes and SPI units must be fully supported until full valve shaft/stem engagement
is achieved and the actuating gearbox or SPI is secured to the valve flange.
⚠Once connected to the valve, each assembly must be assessed on an individual basis for safe handling /
lifting. Never lift the complete combination-valve assembly via the actuating gearbox or SPI.
6Installation
Should the SPI be pre-mounted to the input flange of an actuating gearbox, please see the relevant
installation, operating and maintenance manual for the actuating gearbox for instructions on how to
assemble the gearbox to the valve, and continue to section 7 –Commissioning.
Should the SPI be retrofitted to an existing actuating gearbox in the field, please follow the instructions
below for SPI installation to a valve for a non-thrust taking application, treating the actuating gearbox input
shaft as the valve shaft.
⚠WARNINGS ⚠
⚠Once fully torque-tightened, none of the fasteners in the SPI unit should be re-used. All fasteners with
the exception of the position indicator plate fasteners (D), electrical cover fasteners (E) and internal cam
and cam disc fasteners (H and I) are torque-tightened at the factory. If a fastener is loosened for any
reason, then it should be discarded and a new fastener used in its place.
⚠The SPI must not be used to carry the combined weight of the actuating gearbox and valve during
lifting operations.
Visually check the SPI for signs of damage during transit or storage. Contact Rotork for advice if more serious
damage is observed.

This range of position indicators is supplied to suit the order requirements however, for the optional thrust
taking application, unless specifically requested at the ordering stage, the output sleeve will be supplied
blank and must be machined to suit the equipment to be operated. See Figure 1 –SPI Thrust Taking Output
Sleeve Assembly, Figure 2 –SPI Thrust Bearing Arrangement & Figure 3 –SPI Output Sleeve Machining /
Sealing Faces for the removal and re-fitting of the output
sleeve.
The output sleeve, thrust bearings and washers can be
easily removed from the bottom of the SPI by first
removing the spigot ring. The output sleeve machining
should be concentric to the outside diameters of the
sleeve to ensure correct operation in service. Chamfers
should be provided to aid location with the valve spindle.
All sharp edges should be removed. Following machining,
the output sleeve, thrust bearing assemblies and spigot
ring should be re-fitted to the SPI with the output sleeve
dogs in the correct position to ensure drive from the SPI
output shaft. Applying a thin layer of grease to the faces
marked ‘A’ below will make refitting of the output sleeve
easier.
⚠WARNING –Ensure the correct order of thrust bearing components. Incorrect fitting of the thrust
bearing assemblies may lead to serious damage resulting in significantly reduced performance and life of
the SPI unit.
Important Notes for Figure 3 –SPI Output Sleeve Machining /
Sealing Faces:
A: The surfaces marked “A”can be used for chucking the output
sleeve for machining.
B: The surfaces marked “B”are sealing faces and must be defect
free.
⚠WARNING –Take care when fitting the handwheel to the input shaft to ensure it can be removed again.
Commissioning can only be completed by removing and replacing the electrical cover of the SPI, which
cannot be achieved with the handwheel fitted.
For non-thrust taking applications, the valve shaft should be given a light coat of suitable grease to aid
assembly with the SPI. The SPI should then be fitted by sliding it over the valve shaft (using suitable lifting

equipment as required), ensuring the keyway is correctly aligned with the valve shaft. The SPI baseplate
should sit square on the valve mounting flange and should not place any sideways forces on the output
shaft. If the SPI unit is a tight fit on the valve shaft, it may be necessary to strike the top of the SPI input shaft
with a soft faced mallet. Excessive force should not be used and if there is any possibility of damaging the SPI
unit, it should be removed, the valve shaft and SPI output shaft bore inspected and any tight spots dressed
out where appropriate.
For thrust taking applications, the threaded valve stem must be thoroughly lubricated with a suitable grease
before fitting the SPI. The SPI should then be offered up to the valve stem, and the input shaft rotated to
thread the output sleeve of the SPI onto the valve stem. The SPI baseplate should sit square on the valve
mounting flange and should not place any sideways forces on the output sleeve. If the output sleeve is a
tight fit on the valve stem, the SPI unit should be removed, the valve stem and output sleeve machining
inspected and any tight spots dressed out where appropriate.
For other valve shaft / stem arrangements, please contact Rotork for further advice on installation of the SPI
unit.
⚠WARNING –Do not strike the SPI unit to aid installation for a thrust taking application, as the thrust
bearings may become damaged and will require replacing.
The SPI is supplied with studs and nuts for mounting to the valve or gearbox. If it is desired to replace these
we recommend grade 8.8 fasteners (640MPa yield strength). The mounting nuts or screws should be
torque-tightened to a maximum of 45Nm (33.1 lb ft.) for non-thrust taking applications or 60Nm (44.3 lb ft.)
for thrust taking applications.
Important Note for Figure 4 –Sealant Location Face:
It is recommended that adjoining flanges be sealed on assembly
with silicon sealant. The face marked “C”on Figure 4 –Sealant
Location Face shows where sealant can be applied to the valve
mounting flange.

8Operation
The SPI is used to transmit the torque developed by a hand wheel in order to achieve the torque and / or
thrust requirement of the valve, either directly or through an actuating gearbox, and has been designed for
an operating speed of 12 RPM. It is also used to mechanically display valve position locally and to electrically
signal open / closed valve position to a remote location. There are no operating instructions relating to the
SPI unit itself. The SPI should be operated according to the valve manufacturer’s instructions and the
actuating gearbox manufacturer’s instructions (if fitted).
No running in period is required. Calibration of the unit after initial set up is not required.
⚠WARNING –Under no circumstances should any additional lever device such as a wheel-key, wrench or
extension bar be applied to the handwheel in order to develop more torque or thrust when closing or
opening the valve. This may cause damage to the valve and/or actuating unit or may cause the valve to
become stuck in the seated or back-seated position, or could lead to serious injury. This practice must not
be undertaken at any time.
⚠WARNING –The SPI unit is not designed to be operated by anything other than a hand wheel and as
such has a rated operating speed of 12 RPM. The SPI unit must not be operated with any form of high
speed device (such as air tools, drills, etc.) as this may lead to irreparable damage or serious injury.
9Maintenance
All mechanical cavities are lubricated with Fuchs Renolit CLX2 grease and sealed for life. Annual functional
check of the SPI is recommended. Under normal operating conditions no maintenance is required for the SPI
unit. The required checking interval depends upon the respective application and more frequent checks may
be carried out, this has to be determined by the user dependent on the conditions of use.
All fasteners are fully torque tightened during assembly or commissioning. Once loosened, fasteners should
be discarded and replaced with new and should never be reused. New fasteners should be tightened to the
recommended torques (see section 12). Furthermore, bearings and O-rings must be replaced if disturbed
after commissioning, as they may be damaged during maintenance activities. If any grease is lost or
contaminated as a result of the SPI unit disassembly, this must be replenished using a suitable grease. The
unit must not be operated without lubrication.
Spares kits are available from Rotork. These include all seals, bearings and fasteners and a sufficient
quantity of grease. Contact Rotork with the serial number of the unit to request a spares kit.
This equipment incorporates an anodized outer surface. To avoid the possibility of electrostatic charges,
cleaning must only be carried out with a damp cloth.
Under no circumstances is the electrical assembly (comprising of the PCB, soldered terminals, wires and
switches/sensors) to be altered, disassembled or replaced. For SPI units certified for use in potentially
explosive atmospheres, this assembly is a certified IECEx/ATEX component, and any changes to this
component will invalidate the safety certification of the SPI unit.
All seals, housing components and the input and output shafts are safety critical parts for units in hazardous
areas.
10 Special Tools
No special tools are required for the installation or maintenance of the SPI unit.

PUB132-002-00_0219
11 Spare Parts
As SPI units are sealed and qualified for life, replacement of parts does not extend this qualified life. If it is
desired that an inspection of the SPI unit be carried out, Rotork can perform the inspection and will, where
required, replace all screws, O-rings, bearings and grease when re-building the SPI unit. Please note that all
records relating to spare parts are to be maintained by the unit owner.
